Gold is coveted by many

Gold’s qualities make it one of the most coveted metals in the world. Not only can it be beautifully shaped and sculpted, the yellow metal conducts electricity and does not tarnish. These qualities make it the metal of choice for a wide variety of industries. Let’s take a look at some industrial, medical and technological uses of gold, some of which are truly amazing.

It's been used by dentists for 3,000 years

Gold has been used in dentistry for nearly 3,000 years. The first book published on dentistry, entitled Artzney Buchlein, appeared in 1530. The book suggests dentists fill cavities and rotten teeth with gold leaf.

Gold is not toxic

Thousands of years later gold is still being used for fillings, crowns, bridges and orthodontic appliances. Gold is a bio-compatible metal, meaning it can be placed in contact with a person’s body and not cause harm to one’s health.

Gold's a great conductor of electricity

Gold is a highly efficient conductor of electricity and is used in most electronic devices, including cell phones. Gold contained in connectors, switches and relay contacts allows phones to remain free of corrosion.

You can find 50 cents worth of gold in every cell phone

According to the World Gold Council, a single mobile device contains up to 50 milligrams of gold. That’s a tiny amount but nearly 1 billion cell phones are produced each year. With a gold value of about 50 cents in each phone, that adds up to $500 million dollars in gold each year!

Gold is found in most computers

Gold can also be found in most standard desktop and laptop computers. The precious metal is used in a CPU’s memory chip and motherboard, allowing parts of your computer to receive power and communicate with each other.

Gold has been used in medicine for 4,500 years

The earliest medical use of gold can be traced back to China in 2500 BC. Chinese physicians used pure gold to treat furuncles, smallpox, skin ulcers and to remove mercury from skin and flesh, says GoldBulletin.

Nowadays, it's used to treat arthritis

Today the metal is primarily used to treat patients with arthritis. Gold salts are used to reduce swelling, bone damage and to relieve joint pain and stiffness. It’s a slow process; patients generally receive 22 weeks of gold injections before experiencing relief.

Gold can be flattened into extremely thin sheets

Gold is highly malleable and flexible. Gold can be beaten into thin sheets, only a few millionths of an inch thick. These sheets, known as gold leaf, are displayed on buildings throughout the world, such as St. Michael’s Cathedral in Kiev, Ukraine.

This structure is made of 1.5 tons of gold

India’s Sripuram Golden Temple is the world’s largest golden structure. The spiritual park is made out of 1.5 tons of gold. The gold leafing provides a durable and corrosion-resistant covering, says GoldPrice.com.

It's also found in space suits

NASA also protects its astronauts using gold. Astronauts’ helmets are covered by the extravehicular visor assembly. The visor is coated with a thin layer of gold to filter out the sun’s harmful rays, according to NASA.
